Modeling migration of oligomers from PET
Scientists derive diffusion coefficients for PET oligomers under swelling conditions; compare predictions by Piringer and Welle migration models

New version of FACET published
EU Commission’s Joint Research Centre releases updated version of FACET software enabling exposure estimations for food contact materials; free download available

Long-term migration from PET
Scientists show that for PET bottles accelerated migration tests overestimate real long-term migration; suggest use of migrant- and polymer-specific diffusion parameters instead of default values

Modeling chemical exposure via food
Scientists discuss models available for estimating human exposure to chemicals through food; chemical inputs from processing, packaging, storage, and transportation are underreported

Modeling of migration from LDPE
Scientists determine key parameters for modeling migration of benzophenone and several other contaminants from low density polyethylene into food simulants and foodstuffs; propose revision of worst-case scenario values

Decontamination of recycled polyolefins
Scientists review decontamination of recycled polyolefins, compare it to PET; existing processes need re-examination using high molecular weight surrogate contaminants
